Abstract
Integrated nutrient management for rice (Oryza sativa L.) – rice cropping system in the subhumid subtropical climatic condition was studied at Regional Research Sub-Station (RRS), Chakdaha, Nadia, West Bengal. Considering the system productivity, economics of production and soil fertility condition it may be concluded that maximum production (9.26 and 10.37 t ha−1yr−1 under HYV-HYV and hybrid-hybrid crop sequences, respectively) was obtained when rice crop received 50% recommended doses of nutrients through chemical fertilizer along with 50% recommended doses of nutrients through green leaf manuring during wet season and 100% recommended doses of nutrients through chemical fertilizer during boro season. Under the same treatment combination the net returns/annum were Rs. 24939.25 and Rs. 25875.59 ha−1yr−1 and the returns rupee−1investment were Rs. 1.66 and Rs. 1.62 in HYV-HYV and hybrid-hybrid rice crop sequences, respectively. Under similar conditions soil N, P and K content improved over initial value by 1–17%, 1– 5% and 0 –6%, respectively under hybrid rice-hybrid rice crop sequence.
